Meta-Analysis
BACKGROUND
This systematic literature review and meta-analysis aimed to assess the accuracy, sensitivity, and specificity of dual-energy computed tomography (DECT) of the sacroiliac joint. Bone marrow edema (BME) of the sacroiliac joint is an early manifestation of some diseases, such as ankylosing spondylitis, and is usually examined by nuclear magnetic resonance imaging (MRI); however, MRI can be intolerable for some patients; hence, numerous studies have analyzed DECT examinations.
METHODS
We searched PUBMED, CNKI, and EMBASE in 2023 for articles containing the following terms (DECT) or (DE-CT) or (dual-energy CT) or "dual-energy CT" or (dual-energy computed tomography) and ((sacroiliac joint) or (ankylosing spondylitis) or (sacroiliac arthritis) or (sacroiliitis)). An initial search identified 444 articles, of which 7 met the criteria. Data were extracted to calculate the sensitivity, specificity, and diagnostic odds for analysis using R software.
RESULTS
Out of 291 patients and 577 sacroiliac joints, 429 (74.35%) exhibited BME. All studies used magnetic resonance as the control group. The overall sensitivity and specificity of DECT were 79%, and 92%, respectively, with positive prediction rate of 92.55% and negative prediction rate of 83.73%.
CONCLUSION
DECT appears to be a promising diagnostic tool for detecting BME in the sacroiliac joint and can be used as an alternative examination method for patients in whom MRI is contraindicated.

OBJECTIVES
Summarise the evidence of the performance of the machine learning algorithm in discriminating sacroiliitis features on MRI and compare it with the accuracy of human physicians.
METHODS
MEDLINE, EMBASE, CIHNAL, Web of Science, IEEE, American College of Rheumatology and European Alliance of Associations for Rheumatology abstract archives were searched for studies published between 2008 and 4 June 2023. Two authors independently screened and extracted the variables, and the results are presented using tables and forest plots.
RESULTS
Ten studies were selected from 2381. Over half of the studies used deep learning models, using Assessment of Spondyloarthritis International Society sacroiliitis criteria as the ground truth, and manually extracted the regions of interest. All studies reported the area under the curve as a performance index, ranging from 0.76 to 0.99. Sensitivity and specificity were the second-most commonly reported indices, with sensitivity ranging from 0.56 to 1.00 and specificity ranging from 0.67 to 1.00; these results are comparable to a radiologist's sensitivity of 0.67-1.00 and specificity of 0.78-1.00 in the same cohort. More than half of the studies showed a high risk of bias in the analysis domain of quality appraisal owing to the small sample size or overfitting issues.
CONCLUSION
The performance of machine learning algorithms in discriminating sacroiliitis features on MRI varied owing to the high heterogeneity between studies and the small sample sizes, overfitting, and under-reporting issues of individual studies. Further well-designed and transparent studies are required.

BACKGROUND
The sacroiliac joint is one of the proven causes of low back and lower extremity pain, ranging from 10% to 25% in patients with persistent axial low back pain without disc herniation, discogenic pain, or radiculitis. Despite the difficulty of diagnosis, multiple therapeutic modalities including surgical and nonsurgical interventions have been utilized. Among the interventional modalities, intraarticular injections are commonly utilized.
OBJECTIVE
To evaluate the therapeutic effectiveness of intraarticular injections in the sacroiliac joint.
STUDY DESIGN
A systematic review and meta-analysis of randomized controlled trials (RCTs) and observational studies of the therapeutic effectiveness of intraarticular injections of the sacroiliac joint utilizing the Preferred Reporting Items For Systematic Reviews And Meta-Analyses (PRISMA) checklist.
METHODS
The available literature on therapeutic sacroiliac joint intraarticular injections was reviewed. The quality assessment criteria utilized were the Cochrane review criteria to assess risk of bias, the Interventional Pain Management Techniques - Quality Appraisal of Reliability and Risk of Bias Assessment (IPM-QRB) for randomized therapeutic trials, and the Interventional Pain Management Techniques - Quality Appraisal of Reliability and Risk of Bias Assessment for Nonrandomized Studies (IPM-QRBNR) for nonrandomized studies. The level of evidence was based on best evidence synthesis with modified grading of qualitative evidence from Level I to Level V. Data collection was performed including literature published from 1966 through December 2022, as well as manual searches of the bibliographies of known articles.
OUTCOME MEASURES
Primary outcome measures include pain relief and improvement in functional status at 3 months for a single intervention. Only the studies performed under fluoroscopic guidance, with at least 3 months of follow-up were included. Duration of relief was categorized as short-term (< 6 months) and long-term (> 6 months).
RESULTS
Based on the qualitative and quantitative analyses with a single-arm meta-analysis and the Grading of Recommendations, Assessment, Development and Evaluations (GRADE) system of appraisal, and the inclusion of 11 RCTs (5 positive, 6 negative) and 3 observational studies (2 positive, one negative), the evidence was Level III or fair in managing low back pain of sacroiliac joint origin with sacroiliac joint injections.
LIMITATIONS
This systematic review and meta-analysis are limited by lack of eligible studies, inconsistencies among the available studies, variations in techniques, variable diagnostic standards for inclusion criteria, and finally, the inability to correlate the results and perform an optimal systematic review and meta-analysis.
CONCLUSION
The present systematic review and meta-analysis show an inability to perform conventional dual-arm analysis, whereas a single-arm meta-analysis demonstrated a difference of approximately 3 points on the Numeric Rating Scale (NRS) and 8 points on the Oswestry Disability Index (ODI). However, there were no studies that considered >= 50% relief as the criterion standard. Overall, the qualitative and quantitative evidence combined shows Level III or fair evidence for therapeutic sacroiliac joint injections for managing low back pain of sacroiliac joint origin.

Review
The aim of the present study is to systematically review the current literature about diagnosis and treatment of acute inflammatory sacroiliitis in pregnant or post-partum women. A systematic search was carried out according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. Data about clinical presentation, diagnosis methods and treatment strategies were retrieved from included studies and reported in a table. After screening, five studies on 34 women were included; they were all affected by acute inflammatory sacroiliitis. Clinical examination and magnetic resonance imaging were used to confirm diagnosis. In four studies, patients were treated with ultrasound-guided sacroiliac injections of steroids and local anesthetics, while one study used only manual mobilization. Clinical scores improved in all patients. Ultrasound-guided injections proved to be a safe and effective strategy for inflammatory sacroiliitis treatment during pregnancy or post-partum.
